Ecosystems and Food Webs

One lesson that nature teaches is that everything in the world is connected to other things.
As John Muir famously wrote: 'When we try to pick out anything by itself, we find it hitched to everything else in the universe'.
My current work is fundamentally based on John Muir's quote as I strongly agree, and feel that a lot of people dont seem to have a clear enough understanding of the importance of issues such as biodiversity and ecosystems.
Iv decided to focus my attention on the oceans as, covering more than 75 percent of the Earth's surface — many people once thought of the ocean as a resource that was unlimited and vast. They believed that oceans could provide never-ending supplies of fish and other foods, and absorb infinite quantities of sewage and other pollution. We now know that this is not the case.
Initially my research started with food webs(a food web shows how several food chains are related) as this relates to the theory that all living things are connected; if one animal or plant is affected, all others in the food web eventually will be affected as well.
I then developed this idea to looking at humans dominance on the planets resources as it is evident that human activities are causing dramatic changes to the ocean due to overfishing, pollution and climate change.
